' COMBINED DILATOR AND CATHETER.

Specification of Letters Patent.

Patented May26, 1914.

Application filed June 14, 1913. Serial No. 773,666.

To all whom it may concern Be it known that I, CHARLES L. JOHNSON, acitizen of the United States, residing at Augusta, in the county ofRichmond and State of Georgia, have invented new and useful Improvementsin Combined Dilators and Catheters, of which the following is aspecification.

This invention relates to a combined urethral bougie or dilator andcatheter, its main object being to provide an instrument which willsubserve the functions of separate instruments usually employed for thepurposes.

A further object of the invention is to provide an instrument of thecharacter described which is eflicient for both of its intendedpurposes, and which is simple of construction, convenient ofmanipulation and adapted to be readily cleansed and maintained in anaseptic condition.

The invention consists of the features of construction combination andarrangement of parts, hereinafter fully described and claimed, referencebeing had to the accompanying drawings, in which Figure 1 is aperspective view of the closed instrument. Fig. 2 is a side view of thesame with the jaws thereof spread. Figs. 3, 4 and 5 are verticaltransverse sections on the lines 8-3, 4% and 55 of Fig. 2. Fig. 6 is avertical longitudinal section. Fig. '7 is a top plan view of a slightlymodified form of instrument.

In carrying my invention into practice, I provide an instrumentcomprising a pair of members 1 and 2, which may be arranged insuperposed relation, as shown in Figs. 1 to 6 inclusive, or side byside, as shown in Fig. 7 These members are pivotally connected, as at 3intermediate their ends to provide a pair of jaws l and handles 5. Theinstrument as a whole is longitudinally curved, in the usual manner, andthe forward ends or the jaws are bent or curved upwardly, while thehandles are bent or curved downwardly. A bowed leaf spring 6 is providedbetween the handles 5 adjacent to and immediately in rear of the pivot3, and acts to hold the handles normally spread and the jaws normallyclosed. One end of this spring is seated in a recess 7 in the lowerhandle, while the opposite end of the spring is fitted to work looselyin a recess 8 in the other handle.

For the purpose of adjusting the handles to open and close the jaws 4:,I provide one of the handles with a threaded opening 9 and the otherhandle with a slot or opening 10. Through the slot or opening 10 extendsan adjusting screw 11 which works within the threaded opening 9, wherebythe handles may be moved together against the resistance of the springto spread the jaws 4 apart for a dilating action.

In accordance with my invention, the jaws are longitudinally taperedfrom the pivot toward their forward or introduction ends, and said jawsare provided in their meeting faces with longitudinal channels orgrooves 12, forming a longitudinal passage. The side walls of thesegrooves are provided with notches, arranged in advance of the pivot andadjacent the rear ends of the jaws, at a point where the instrumentprojects from the organ when inserted for use. These notch-es areadapted to register to form lateral passages for the discharge of thesecretion when the device is employed as a catheter.

It will be seen from the foregoing description that the inventionprovides a simple form of instrument which may be used as an ordinarybougie or dilator, and which may also be used as a catheter, thusproviding a single instrument adapted to perform such functions. It willalso be seen that the device is simple of construction, capable of beingconveniently manipulated, and also capable of being readily cleansed andmaintained in an aseptic condition.

shown in Fig. 7 the members of the instrument are arranged side by sideinstead of in superposed relation as in Figs. 1 to 6, in elusive, thedivision being vertical instead of horizontal, as will be readilyunderstood. Otherwise the construction of the two forms of the deviceherein disclosed is exactly the same.

I claim A combined urethral dilator and catheter comprising a pair oflongitudinally curved jaws, said jaws being of channeled formation andhaving their channeled sides facing each other to form, when the jawsare closed,

In the modified form of my invention a longitudinal passage, handlesconnected closed, and means for adjusting the handles with the jaws andhaving portions pivotally to hold the jaws open. 10 connected andarranged to close the rear end In testimony whereof I affix my signatureof the passage when the jaws are closed, the in presence of twowitnesses.

meeting edges of said jaws being provided CHARLES L. JOHNSON.
